Hi Chris,
              Regarding this impulse, one has to think of the so many 
reports of BL being seen exiting or hanging around fireplaces; If you look 
at the soot covered chimney interior you can also look at it as a potential 
waveguide or resonant space
with all kinds of trace metals available, plus of course carbon. Like any 
metal ringing on a harmonic, such a cavity would, too. Especially if the 
chimney was directly hit by lightning.
So, you have resonance, containment, high energy impulse, conductive 
material  and a post processing exit all in one place. I've often wondered 
about that.
Mike
